The Authority in Potassium and Magnesium

The world of potato

Intended use and yield expectation are key factors for optimising crop nutrition in potatoes: Potassium (K), magnesium (Mg), sulphur (S) and phosphorus (P) serve as the foundation for quality, yield and storage qualities of potatoes; foliar applied trace elements such as boron and manganese provide the “icing on the cake”. more

Current topic

Alternaria in potatoes – Magnesium helps to prevent the disease. In 2010, there was a marked increase in the incidence of alternaria infections in potatoes. Magnesium fertilisation strengthens the resistance against this important fungal pathogen. more

On 9 September 2010, at the PotatoEurope, the reigning German Miss Potato, Melanie Wölm, will draw the top prizewinners of the K+S KALI GmbH’s great summer raffle “Die fleißigen Hände” (Busy Hands). more

Potato cultivation I

Potassium fertilisation essential in potato production. In the production of starch and industrial potatoes, an insufficient supply of potassium can quickly result in storage and quality problems. This has been proved by comprehensive field trials. more

Potato cultivation II

Balanced nutrient supply essential for qualityp. In addition to improving yield, a balanced nutrient supply also safeguards potato quality Potassium, magnesium and boron play important roles. more

Trial potato cultivation

On the trial site Lüsche (Süd-Oldenburg, Germany) the tuber yield could be increased by 17 percent due to a potassium sulphate fertilisation of 300 kg K₂O and a simultaneous magnesium fertilisation. more
